NEC Corporation has announced the launch of a project to develop an Orbital Transfer Vehicle (OTV) following its selection by the Japan Aerospace Exploration Agency (JAXA) for a grant under the theme “Technologies for Realizing Flexible Mobility in Space.” This initiative aims to establish the first implementation of an OTV in Asia.
An OTV is a spacecraft designed to transport satellites to their intended orbits, such as geostationary or lunar orbits, after separation from their rockets. Traditionally, satellites rely on their own engines and fuel to reach these destinations. However, an OTV can perform this task, allowing even small satellites without large engines to be deployed to distant orbits. Additionally, OTVs can transport multiple small satellites simultaneously, enhancing transport efficiency.
The development of OTVs is expected to accelerate space development by promoting future space economies and encouraging new operators to enter the sector. NEC's extensive experience in spacecraft development, including projects like the geostationary satellite “Kizuna” and the lunar orbiter “Kaguya,” will be instrumental in this endeavor.
NEC plans to conduct market feasibility studies, conceptual design, and demonstrations for OTVs by the end of fiscal year 2027. The company aims to develop a demonstration model by fiscal year 2028, with in-space demonstrations targeted for fiscal year 2032. The ultimate goal is to bring the technology to practical use, expanding Japan's space industry and exploring new frontiers.
